manufacturer’s specifications. The charge for each cell should be checked with a hydrometer. A

4.A chirping sound from the control box will accompany the red light, indicating that the battery may require attention or replacement. Voltage is only an indicator of battery condition and may not reflect the true condition of the battery. See Maintenance for instruction on assessing battery condition.

5.A single thirty-second tone will sound when power to the system is interrupted. The unit will reset automatically when power is restored. A three-second tone will sound every time the pump starts.

Always disconnect the electrical supply before attempting to install, service, relocate or perform any maintenance. If the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power application. Failure to do so could result in fatal electrical shock. Only qualified electricians should repair this unit. Improper repair could result fatal in electrical shock.

1.Once a month, check battery condition.

2.Unplug the wall charger.

3.For batteries with top caps that can be removed, the electrolyte level should be checked and filled to

specific gravity of 1.265 indicates the battery is at full charge. If the specific gravity of any of the cells varies more than .050, the battery should be replaced.

NOTE: An inexpensive hydrometer can be purchased at an automotive parts dealer.

4.Inspect the terminals and clamps for corrosion and tightness. Clean and tighten as required.

5.Unplug the main pump and fill sump with water until back up pump turns on. Repeat process two times to be sure pump is operating normally.

6.If pump operates normally, plug charger into wall outlet, turn on main pump. If pump fails to operate normally, see Troubleshooting guide and correct problem. Repeat step 5.

Troubleshooting Chart

Symptom Possible Cause(s) Corrective Action

Pump won’t run	1.	Connections not secure
	2.	Low or defective battery
	3.	Float switch unable to swing up and
		down as needed
	4.	Defective or blown fuse

1.Check all connections

2.Check battery and replace if low or defective

3.Check that float switch tether is long enough to allow pump to operate

4.Check internal fuse located inside the control box. Pull the charger from the wall outlet and remove. If the fuse is blown, replace it with a 15 amp automotive type fuse

Motor hums but	1. Defective battery
pump won’t run	2. Impeller is locked

1.Check battery and replace if low or defective

2.Unplug pump and check to see if impeller is free to turn. If impeller is locked, remove the 4 screws on the bottom of the pump to release the housing around the impeller. Remove the obstruction. Reassemble pump and reconnect

Pump runs but	1. Check valve missing or improperly
pumps very little		installed
or no water
	2.	Obstruction in discharge pipe
	3.	Pump not rotated 30˚
	4.	Pump air locked
	5.	Discharge pipe length and/or height
		exceeds capacity of pump
	6.	Low or defective battery

1.Check to make sure a check valve is installed and functioning between primary pump discharge and Standby Sump Pump tee fitting

2.Check for obstruction and clear if necessary

3.Check that pump is rotated 30˚ in tee fitting as shown in Figure 3

4.The impeller housing has a small hole on its side. This hole must be open for the pump to prime. With the pump unplugged, remove the 4 screws on the bottom of the pump to release the housing around the impeller. Clean out the hole and replace cover

5.If discharge is too high, a separate line may be required with a lower discharge height

6.Check battery and replace if low or defective

Pump cycles too	1.	Tether length too short on float
frequently		switch
	2.	Main check valve located between the
		discharge of the primary pump and
		the Standby Sump Pump tee fitting or
		the Standby Sump Pump flapper valve
		not installed or working properly

1.Tether length should be at least 2”. Adjust if necessary CAUTION: Ensure tether will swing freely without obstruction

2.Install check valve or repair as required
